12 Questions
What is the term used to describe motion along a curved path?
Circular motion
What are the two fundamental concepts studied in circular motion?
Rotation and revolution
How does rotation differ from revolution?
Rotation does not change the position of the object, but revolution does.
What is the axis of rotation for an object?
Internal
Give an example of an object undergoing rotation.
Hand of clocks, Spinning top, etc.
What causes day and night on Earth?
Rotation of Earth
What is the key difference between rotation and revolution?
Rotation occurs around an internal axis within the object, while revolution occurs around an external axis outside the object.
How is Earth's rotation direction different from its revolution direction?
Earth rotates from west to east, completing it in approximately 24 hours. On the other hand, Earth revolves around the Sun in a counterclockwise manner, taking around 365 days.
Provide examples of objects that demonstrate rotation and revolution.
Examples of rotation include clock hands and spinning tops. Examples of revolution include cars rounding a curve and kids on a merry-go-round.
Explain the concept of period in revolution.
The period in revolution is the time taken by an object to complete one full trip around a circle or orbit.
What is the relationship between degrees and direction of rotation?
Clockwise rotation is expressed in negative degrees, while anticlockwise rotation is expressed in positive degrees.
How can you differentiate between rotation and revolution based on the location of the axis?
Rotation occurs around an axis within the object, while revolution occurs around an axis external to the object.
